[Bug 36842] New: Can't set a static crontrol's text to empty by pssing NULL pointer
http://bugs.winehq.org/show_bug.cgi?id=36842 Bug ID: 36842 Summary: Can't set a static crontrol's text to empty by pssing NULL pointer Product: Wine Version: 1.6.2 Hardware: x86 OS: Mac OS X Status: UNCONFIRMED Severity: minor Priority: P2 Component: comctl32 Assignee: wine-bugs(a)winehq.org Reporter: tulio150(a)mailinator.com On Windows, when you call SetWindowText(NULL) on a static control, it clears the control to an empty string. On Wine the call has no effect, the text just remains as it was before, you have to call SetWindowText("") to clear the static control. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=36842 --- Comment #1 from Nikolay Sivov <bunglehead(a)gmail.com> --- Originally Static control is a user32 control. Do you mean that one or you're actually using Static from comctl32 v6? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

This behaviour is well-known to Win32 programmers and was the same in Win16. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=36842 --- Comment #4 from Henrik Haftmann <heha(a)hrz.tu-chemnitz.de> --- Created attachment 50220 --> https://bugs.winehq.org/attachment.cgi?id=50220 Simple Win32 program that shows the effect When the user presses "Click me", a SetWindowText() / SetDlgItemText() call with NULL string parameter is generated with different target windows, also for the main window. While main window's WM_SETTEXT message processing, a MessageBox() shows the actual lParam value, which is indeed 0. The different child windows are STATIC, BUTTON, EDIT, and COMBOBOX. The Windows behaviour is that all controls are cleared out, even the top-left static control. The windows screenshot shows the controls before the button is clicked. The wine behaviour is similar, but the static control remains untouched. Therefore, I can confirm the bug. Furthermore, the behaviour of shlwapi.dll's wnsprintf() is different (i.e. a second bug): While Windows substitutes nothing for "%s" format specifier, wine substitutes the null pointer with "<null>". Some software may rely on the fact that string null pointers are handled like zero-length strings in many (or possibly all) places of the Win32 API. By the way, the second button "GetClassName" works the same way in Windows and wine, therefore, it shows correct operation for integer WNDCLASS class names, i.e. excellent emulation of a very basic but rarely used feature. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
